Chassis self-unlock mechanism

Abstract

A chassis self-unlock mechanism includes a tray, a handle assembly and a locking arm. The handle assembly includes a fixed base, a handle and a slider connected to the handle. The fixed base is fixed on the tray, and the slider is movably connected with the fixed base. The locking arm is attached to the tray, an end of the locking arm is fixed to the tray, an actuating slope inclined with respect to the locking arm is formed on the locking arm, a latch laterally protrudes from the locking arm, and the latch protrudes out of an outer surface of the tray. The slider is movable to push the actuating slope, so that the locking arm is bent, and the latch retracts into the tray.

What is claimed is: 
     
       1. A chassis self-unlock mechanism, comprising:
 a tray; 
 a handle assembly, the handle assembly including a fixed base, a handle and a slider connected to the handle, the fixed base being fixed on the tray, the slider being movably connected with the fixed base; and 
 a locking arm, the locking arm being attached to the tray, an end of the locking arm being fixed to the tray, an actuating slope inclined with respect to the locking arm being formed on the locking arm, a latch laterally protruding from the locking arm, the latch protruding out of an outer surface of the tray, wherein the slider is movable to push the actuating slope, so that the locking arm is bent, and the latch retracts into the tray, 
 wherein a slide groove is formed on the fixed base, and the slider is received in the slide groove and is movable along the slide groove; 
 wherein the actuating slope is received in the slide groove. 
 
     
     
       2. A chassis self-unlock mechanism, comprising:
 a tray; 
 a handle assembly, the handle assembly including a fixed base, a handle and a slider connected to the handle, the fixed base being fixed on the tray, the slider being movably connected with the fixed base; and 
 a locking arm, the locking arm being attached to the tray, an end of the locking arm being fixed to the tray, an actuating slope inclined with respect to the locking arm being formed on the locking arm, a latch laterally protruding from the locking arm, the latch protruding out of an outer surface of the tray, wherein the slider is movable to push the actuating slope, so that the locking arm is bent, and the latch retracts into the tray, 
 wherein a slide groove is formed on the fixed base, and the slider is received in the slide groove and is movable along the slide groove; 
 wherein a blocker is disposed on the other end of the locking arm, the actuating slope is formed on the blocker, and the blocker is received in the slide groove. 
 
     
     
       3. The chassis self-unlock mechanism of  claim 2 , wherein the slider is movable to push the actuating slope so as to push the blocker out of the slide groove. 
     
     
       4. The chassis self-unlock mechanism of  claim 3 , wherein a pushing slope is formed on the slider, and the pushing slope is in contact with the actuating slope. 
     
     
       5. The chassis self-unlock mechanism of  claim 4 , wherein when the slider moves to the point that the pushing slope is separated from the actuating slope, the slider retains the blocker immobile outside the slide groove. 
     
     
       6. A chassis self-unlock mechanism, comprising:
 a tray; 
 a handle assembly, the handle assembly including a fixed base, a handle and a slider connected to the handle, the fixed base being fixed on the tray, the slider being movably connected with the fixed base; and 
 a locking arm, the locking arm being attached to the tray, an end of the locking arm being fixed to the tray, an actuating slope inclined with respect to the locking arm being formed on the locking arm, a latch laterally protruding from the locking arm, the latch protruding out of an outer surface of the tray, wherein the slider is movable to push the actuating slope, so that the locking arm is bent, and the latch retracts into the tray, 
 wherein a through slot is formed on the fixed base, a slidable fastener is protrudingly disposed on the slider, and the slidable fastener is inserted through the through slot to be movable along the through slot. 
 
     
     
       7. The chassis self-unlock mechanism of  claim 1 , wherein the locking arm is attached to an inner surface of the tray, the tray includes a through hole, and the latch is inserted through the through hole to protrude out of the outer surface of the tray. 
     
     
       8. A chassis self-unlock mechanism, comprising:
 a tray; 
 a handle assembly, the handle assembly including a fixed base, a handle and a slider connected to the handle, the fixed base being fixed on the tray, the slider being movably connected with the fixed base; and 
 a locking arm, the locking arm being attached to the tray, an end of the locking arm being fixed to the tray, an actuating slope inclined with respect to the locking arm being formed on the locking arm, a latch laterally protruding from the locking arm, the latch protruding out of an outer surface of the tray, wherein the slider is movable to push the actuating slope, so that the locking arm is bent, and the latch retracts into the tray, 
 wherein the fixed base is disposed on the outer surface of the tray.
